Dr. Jeff Guy issued a statement through the university announcing the news.

Guy affirmed what Head Coach Steve Spurrier had said earlier-- Lattimore had hyperextended his knee. The doctor added there were no fractures or additional injuries, and Lattimore's other surgically repaired knee was not hurt.

The school adds that Lattimore is resting comfortably and will continue to be evaluated over the course of the week. Guy says Marcus has already begun "the process of rehabilitation prior to surgery and to his eventual return to football."

Earlier in the day, Spurrier also gave information on Lattimore's condition during a teleconference with reporters.

Lattimore was injured Saturday during the Gamecocks' 38-35 win over Tennessee. In the second quarter, Lattimore was carrying the ball when he was hit high by one Tennessee defender, then hit around the knee by another.

Video replays showed the leg bending to the side at an extreme angle. He was carted off the field and later was taken to the hospital by ambulance.

Spurrier said he visited Lattimore Sunday morning, that that the junior had a good attitude.

"We're optimistic his football days are still ahead of him," Spurrier said. "It's going to take some time of course."

According to the coach, players have come back from this type of injury in the past and have had productive careers. However, he did say the road back will be long, and it's not clear if Lattimore could even play next year at this point.

Spurrier also discussed the possibility of a medical redshirt. He says ultimately, it will be up to Lattimore to make his own decision.

"He knows what the road ahead is, and we're all hoping and praying he'll be back," Spurrier said.

Spurrier acknowledged the outpouring of support for Lattimore since the injury. "[Marcus is] maybe the most popular Gamecock we've ever had here."

In a display of great sportsmanship, Tennessee players took to field to check on Lattimore Saturday, and many of his Gamecock teammates attempted to comfort him.
